I think the "Days Not Home" system may have to be revisited as the game expands. Right now, if the MC goes around and visits every "home" he has, bangs the woman and then leaves for the next place, he gets yelled at a lot. Like, by the time he's made it through the list of girlfriends from first to last, the first one is angry at him again. You could make it around to everyone, I suppose, if you just say "hi" and run to a waystone to go to the next place, but if you actually want to interact...
And of course, if you have to leave for a quest that might take a day or more, you get everyone mad at you.
If the dev plans to expand the world and add more women, we may need either more time before they get mad at us, or a longer-lasting "keep them happy" solution.
